Hornberg Castle was probably originally built in the late 12th century. The first mention of the castle dates from 1184. In 1259 lords of Hornberg sold the castle to the bishop of Speyer. Since 1612 it has been owned by the 12th generations of Gemmingen barons. Today the castle is a hotel.
Hornberg originally consisted of two separate castles. Between them was a bailey. Around 1510, both castles were enclosed together with the a common wall as an additional attachment of Conz Schott of Schottenstein.
The Jan Hus Memorial stands at one end of Old Town Square. The huge monument depicts victorious Hussite warriors and Protestants who were forced into exile 200 years after Hus, and a young mother who symbolises national rebirth. The monument was so large that the sculptor designed and built his own villa and studio where the work could be carried out. It was unveiled in 1915 to commemorate the 500th anniversary of Jan Hus' martyrdom. The memorial was designed by Ladislav Šaloun and paid for solely by public donations.
Born in 1369, Hus became an influential religious thinker, philosopher, and reformer in Prague. He was a key predecessor to the Protestant movement of the sixteenth century. In his works he criticized religious moral decay of the Catholic Church. Accordingly, the Czech patriot Hus believed that mass should be given in the vernacular, or local language, rather than in Latin. He was inspired by the teachings of John Wycliffe.
